From a practical viewpoint, clinical bacteriology can be subdivided into three main activities. First and foremost is detection, isolation, and identification of pathogens. This is usually achieved by culture of specimens on specific media in defined conditions, accompanied by microscopy and tests of biochemical activity of an isolate. Second is the determination of antibiotic susceptibility, a...

During bistable vision, perception oscillates between two mutually exclusive percepts despite constant sensory input. Greater BOLD responses in frontoparietal cortex have been shown to be associated with endogenous perceptual transitions compared with "replay" transitions designed to closely match bistability in both perceptual quality and timing. It has remained controversial, however, whether...

BACKGROUND Processing stimuli in one sensory modality is known to result in suppression of other sensory-specific cortices. Additionally, behavioral experiments suggest that the primary consequence of paying attention to a specific sensory modality is poorer task performance in the unattended sensory modality. This study was designed to determine how focusing attention on the auditory or visual...

A marine fibrinolytic compound FGFC1 enhancing fibrinolysis was obtained involving enzymatic kinetic parameters of a reciprocal activation system with a single chain urokinase type plasminogen activator and plasminogen. FGFC1, a kind of bisindole alkaloid from a metabolite of the rare marine fungi Starchbotrys longispora FG216, modulated enzymatic kinetic parameters including the fibrinolytic r...

Kinetic and thermodynamic studies reveal that the property of significantly enhanced catalytic activity with colloidal stability is attributed to an efficacious means of tuning enzyme-substrate association by varying with the rate constants in the presence of functionalized gold nanoparticles.

Novel hollow mesoporous @M/CeO(2) (M = Au, Pd, and Au-Pd) nanospheres are created. The nanospheres can be used as effective nanoreactors with superior catalytic activity and stability for reduction of 4-nitrophenol due to their hollow mesoporous structural features.

The experiments set forth here establish the fact that the heat of the inflamed part has its origin primarily in the local biochemical activity of the cellular elements which participate in the inflammatory process. The inflammatory hyperemia, instead of being the necessary and constant source of the inflammation must be considered a natural physiological compensation for the abnormal local cal...

A facile aerosol-spraying approach was developed to prepare mesoporous BiFeO(3) hollow spheres with enhanced activity and durability in visible photocatalysis.

Benzo[d]isoselenazol-3-ones N-substituted with sterically hindered diamagnetic and paramagnetic five- or six-membered nitroxides or their precursors, including ring-opened diselenides, exhibit synergism in glutathione peroxidase (GPx) activity.

Stress induces several temporally guided "waves" of psychobiological responses that differentially influence learning and memory. One way to understand how the temporal dynamics of stress influence these cognitive processes is to consider stress, itself, as a learning experience that influences additional learning and memory. Indeed, research has shown that stress results in electrophysiologica...
